DZH series coal/biomass fired steam boiler realizes almost zero pollution with the use of special dust collector solution. This series boiler is single drum horizontal type shell boiler, the combustion equipment is moving grate. The fuel could be II class bituminous coal and biomass fuel, the diameter of coal should be 6-25mm, and ash content should be less than 32.4%, and for the biomass fuel, carbon content should less than 50%, sulphur content less than 0.08%, and ash content less than 3%.
Working principle
The horizontal hand-fired biomass steam boiler is composed of a shell, a head, a furnace liner, a furnace roof, a U-shaped ring, a cupola, etc. The combustion chamber is arranged in the furnace liner, and the furnace is divided into two upper and lower chambers with a refractory concrete furnace arch. In the combustion chamber, the flue gas generated from the lower combustion enters the secondary combustion chamber through the throat of the refractory concrete furnace arch and is mixed with the secondary air input from the upper furnace door to be fully combusted. The high temperature flue gas generated is radiated and heat exchanged by the heating surface of the furnace. After that, convection heat exchange is performed again through the annular smoke box, and finally discharged into the atmosphere through the chimney.
Applicable fuel This product uses a chain grate. The applicable fuel is shaped pellet fuel. A small amount of wood slats and blocks can be added, or it can be mixed with coal.

(1) The pot barrel is composed of arch tube plate and threaded smoke pipe, so that the pot barrel is changed from a quasi-rigid body to a quasi-elastic body structure, and the stretch parts in the tube-plate area are eliminated to reduce the stress.The smoke pipe in the tube plate is changed from two return journey to single return journey, which solves the problem of crack in the tube plate.
(2) The bottom of the pot is arranged with an ascending pipe row, which eliminates the stagnant area at the bottom of the pot and makes the mud residue not easy to deposit. The high temperature area of the pot can be well cooled to prevent the bottom bulge of the pot.
(3) High efficiency heat transfer threaded smoke pipe is adopted to enhance the heat transfer effect and achieve the characteristics of boiler heating up and rapid pressure boost, thus improving the thermal efficiency of the boiler.
(4) Compact structure, compared with the same type of boiler, the shape size is small, save investment in boiler house infrastructure.
(5) Stable operation, convenient adjustment and sufficient output.
(6) The threaded smoke pipe is used to enhance the heat transfer, which improves the heat transfer coefficient and thermal efficiency, because the smoke has a disturbance effect in the pipe.Smoke tube is not easy to accumulate ash, play the role of cleaning.
The fuel can be biomass pellet, wood chips, waste wood, sawdust, corn stalk, rick husk, biomass pelelt
Application for biomass steam boiler 
Wood fired steam boiler has high heating temperature, low working pressure, energy saving, and can be widely used in various industrial heating processes. Coal fired boiler is suitable for painting room, drying box, drying tower painting line and other purposes.It is especially suitable for central heating in urban residential areas, industrial production, enterprises and institutions, schools, hotels, bath centers and other places where heating, hot water and steam are needed.

1. What are the differences between vertical type boiler and horizontal type boiler with the same capacity?

1. Structure of vertical boiler is compact, occupy a limited area,

2. Convenient on installation and removal.

3. Low cost and investment on capital construction. Steam exhausted fast and sufficient.

1. The combustion space of horizontal is big, fuel can be burned completed.

2. The thermal efficiency is higher than the vertical boiler,

3. Horizontal type: less thermal loss, stronger output, and higher steam quality.

2. What are the limitation (size, humidity, chemical element concentrations) of coal fuel/solid fuel/wood fuel?

Size requirement of coal:6-25mm

Size requirement of blending coal: <50mm (the coal less than 6mm should less than 30%)

Diameter of biomass particle: 6~10mm, length: 25~50mm, water content < 15%, ash content < 2%, sulphur content<0.07%, chlorinity <0.07%, nitrogen content < 0.5%

3. What is the size of furnace door and blower hopper?

Size of furnace door:

Standard elliptical furnace door:300*800*1500

Blower hopper size:

2 tons conical hopper: 1400*800*1500

4 tons conical hopper: 2200*1400*1500

4. What is the combustion mode of coal/biomass fired boiler?

The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.
